With stable product quality and advanced manufacturing processes, we provide safe, durable and efficient pipeline solutions for various infrastructure construction projects.
The PP-R Diamond Blue composite pipe series uses food-grade Nordic chemical PP-R pure raw materials. It effectively solves the problem of scale and impurities adhering to the pipe wall with a large water flow. It can ensure water safety throughout the entire service life of the pipe and prevent scale and impurities from adhering and accumulating inside the pipe, truly achieving the dual function of self-cleaning water and preventing mold.
Pipe Structure:
Blue Shield Protective Layer: Prevents ultraviolet rays, avoids aging and embrittlement, and provides stronger pressure and impact resistance.
Reinforcing and toughening layer: Precision fiber composite, high strength, high rigidity, high temperature resistance, and bending resistance.
Shunshui Cleaning Layer: A national patented high-flow Shunshui system effectively solves the problem of scale and impurities adhering to pipe walls, providing highly efficient cleaning and protection.

Excellent Efficiency And Meticulous Attention To Detail
Made of European standard CW617N brass, it is integrally stamped and formed on a high-precision production line. The thickness and structure of the copper inserts have been reinforced, and each copper insert can fit seamlessly with PPR, ensuring the quality of the product.
CW617N refined copper insert: Nickel-free to prevent heavy metal leaching; physically and mechanically designed structure; dense and high strength; tensile and crack resistant.
High-polymer energy-concentrating pressure ring: Water-locking and sealing design; made of materials specifically for high-precision applications; leak-proof, anti-fraying, and waterproof hammer-resistant.
Reinforced wide ribs and unique waterproof dovetail groove design: Enhances anti-twisting performance, ensuring a tight bond between copper and plastic, preventing leakage.

Product Advantages:
◆ Imported Raw Materials, Guaranteed Quality
Using high-quality polypropylene raw materials from Borealis, ensuring high purity with no added impurities, no recycled materials, odorless, non-toxic, safe, and environmentally friendly, with no leaching during water flow.
◆ Reinforced Core, Safe Use
The red middle layer of the pipe uses a high-polymer material formula for toughening technology, enhancing explosion-proof performance and effectively resisting cracking, ensuring long-term safe use of the pipeline system.
◆ Precision Welding, Leak-Proof
Designed with an S2.5 pressure rating, providing stronger pressure resistance, standardized precision heat fusion socket welding ensures that the pipes and fittings are of the same material, improving the water system’s sealing performance and preventing leaks.
